1 Claim. (Cl. 20S-44) The invention relates to a box made of transparentmaterial and having a paper bottom, as described in the presentspecification and illustrated in the accompanying drawing that formspart of the same.

The invention consists essentially of the novel features ofconstruction, as pointed out in the claim for novelty following adescription containing an explanation in detail of an acceptable form ofthe invention.

The objects of the invention are to furnish a box made of transparentmaterial that will stand up without support; to provide a box which willdisplay the contained material most eiectively; to furnish a transparentbox with a paper bot- 'tom and a beaded top thereby adding to therigidity of the box; to provide a box which offers all the advantages ofan all transparent box but overcomes some of the Weaknesses of the alltransparent boxes; to furnish a box which, on account of its rigidity,will have a long life and can be re-used to hold trinkets and many otherthings, and generally to provide a box that will be of great value tothe manufacturers, the retailers, and the public at large.

It is well known that during the last few years, the use of transparentmaterial for packaging purposes has spread very widely. Most of thistransparent material is used in a lightweight,

(about M000" thick) in sheets which are well Y known to everyone asCellophane. 'I'he Cellophane wrapping, however, is not satisfactory forcertain articles, so that quite a lot of boxes are made from atransparent material in such Weights as 71/2/1000 and 10/ 1,000".'I'hese are called semi-rigid transparent containers.

These semi-rigid boxes are ideal for certain products but their use hasbeen retarded for two or three reasons. One is that they cost a greatdeal more than paper boxes, chiefly because the .transparent material ismuch more expensive than paper. The second reason is that they lackrigidity; this has meant that, in time and under certain weatherconditions, the boxes are warped out of shape.

In the present invention, the cost of the material used is decreasedwithout aiecting the visibility to any extent and the construction ofthe box as hereinafter described adds to the rigidity of the box.

In the drawing, Figure 1 is a. plan view of the transparent blank strip.

Figure 2 is a perspective view of the blank strip shown in Figure 1.

Figure 3 is a fragmentary perspective view of the strip showing the topand bottom edges folded over.

Figure 4 is a perspective view of the transparent cover.

Figure 5 is a perspective view of the box with n the paper bottom. Y f

Figure 6 is a perspective view of the paper base.

Figure 7 is a perspective view of the complete box.

Like numerals of reference indicate corresponding parts in thevarious-figures.

Refer'ing to the drawing, the box I5 is made of a continuous transparentstrip I6, a transparent cover II', a paper bottom I8 and a paper baseI9; the cover may be made of paper if desired but will preferably be oftransparent material, as shown in the drawing. The continuoustransparent strip I6 has the crease lines 2li, 2l, 22 and 23 and theflap portion 24; in the creasing operation the corners 25 are cut at thetop to allow for the bead 26 to fold. The top edge of the strip is thenfolded over the line 21. 'I'he bottom edge is cut, as shown by thenumeral 28, and is then folded out at right angles to the sides on theline 29 forming the inturned edges 30, as shown in Figure 2.

In the operation of this invention, the blank strip is rst creased atthe right spots to fold for the desired size of box, and, as describedabove, the beaded top is formed and the bottom edge is folded, afterwhich the strip is bent where creased at the corners and the flap iscemented. The transparent sides of the box are then put into the paperbase I9 of the required size and the other paper member or bottom I8,which is cut to flt tightly on the inside of the box, is inserted. Wherethis paper bottom I8 is'glued or stuck to the base I9, it locks thetransparent inturned edges 30. The ribbon 3i of a suitable colour may beapplied to the box,A and it can be tied over the cover II, therebyadding to the attractiveness of the box, as shown in Figure 7.

It will be seen that the paper bottom decreases the cost of the materialused without affecting visibility to any extent, and it adds to therigidity of the box, and as the transparent material is a n continuousstrip, there is no waste as is the case when blanks are cut to maketransparent boxes in the regular way. The beaded top adds furtherrigidity to the box and this allows for the use of a paper cover, ifdesired.

Another important feature of this invention is that there is only onelap to cement, which saves labour and makes the contents more visiblethan a bead and the lower flanges forming a securing 10 base. a paperbottom secured to the lower flanges, a paper base adapted to enclose thepaper bottom and the lower portion of the box walls, a cover adapted toenclose the upper portion of the box walls, and a ribbon adapted totransversely straddle the paper base and located between the paper baseand paper bottom and having its free ends adapted to be fastenedtoegther around said cover.
